Illumination accessory assembly for vacuum cleaner

ABSTRACT

An illumination accessory assembly for vacuum cleaner includes a transparent extension having a first end capable of releasable connection to a vacuum cleaner hose and having a distal vacuum cavity intake end. A LED is positioned so the LED illumination transverses the transparent extension medium and exits the distal end and walls of the transparent extension. The invention provides the operator an illuminated clear line of sight around and through the transparent extension of the area to be cleaned and illuminates the contents in the initial vacuum cavity of the transparent extension for improved operator cleaning efficiency.

BACKGROUND OF THE INVENTION

The operation of cleaning of dust, loose dirt, etc. in dimly lit or confined areas is often difficult to perform using a vacuum cleaner with conventional attachments. Various vacuum cleaner hose attachments with illumination means have been proposed to improve the function of the operation of cleaning in the areas described. Although effective in illuminating the surface area intended to be cleaned, existing devices exhibit obstructed operator lines of sight that impact the effectiveness of the operator to clean the illuminated surface.

Therefore, it is desirable to have an illumination accessory for a vacuum cleaner hose that can illuminate the surface to be cleaned that exhibits a clear operator line of sight around and through the attachment device. It is also desirable to have this device illuminate the interior of the initial vacuum cavity of the attachment to provide the operator an illuminated line of sight of the contents being vacuumed.

BRIEF SUMMARY OF THE INVENTION

It is the object of the present invention to provide an initial vacuum intake accessory for a vacuum cleaner hose that utilizes a transparent extension that is a vacuum passage device that is also a lighting device for illuminating a surface to be cleaned, whereby an operator can find dust and loose dirt in a dimly lit or confined location with a clear line of sight around and through the transparent extension of the area to be cleaned. It is also the object of this present invention to provide illumination of the initial vacuum cavity inside the transparent attachment, whereby an operator has an illuminated clear line of sight of the contents being vacuumed.

In order to obtain the aforementioned objective, it is also the object of the present invention that the light means, such as a Light Emitting Diode (LED), be positioned in line with the transparent extension medium wherein the transparent extension medium is the path for the light means illumination to transverse to the distal end and out the distal end to provide utility lighting.
